When i was a kid stores sold a toothpaste for all the different age ranges, and they’d add a colour each time you got a bit older like you were graduating to another aspect of tooth protecion. As such, I never actually experienced such a brutal wake-up call as this image suggests, because strange machinations were put in place to ween me off kiddy toothpaste… and now I’m wondering if this was a marketing scheme or if my parents actually did hunt down training wheels toothpaste to ease me into things.
